hondo Posted August 2, 2009 Share Posted August 2, 2009 I am trying to get the dimensions on a 3/4 id whistle rocked spindle, before I turn my SS rod down I would like to get some correct dimension attached is my drawing and I want to make the tube 3.75 inches long, that way I can cut my BP tubes in half and make 2 instead of the 5.5 inch and waste part of the tube, Am I close to the correct dimensionswhistle_rocket_tooling.ppt Link to comment Share on other sites More sharing options...
Miech Posted August 3, 2009 Share Posted August 3, 2009 Are you planning to make benzoate or salicylate whistles? For benzoate you might want to have your spindle about an inch longer to have somewhat more thrust. For salicylate you are near what works best with my whistles.
